| Summary: | 0001159: Byte-code produced for _resin_compat_class_0 | ||||
| Description: |
(rep by L Plaetinck) We are working on a Java profiling tool and ran into some problems when instrumenting some of the Resin classes.One of the offending classes seems to be com.caucho.doc.JavadocRedirectServlet, especially the method _resin_compat_class0(): private static java.lang.Class _resin_compat_class_0(); Code: Stack=2, Locals=0, Args_size=0 0: getstatic 0000221; //Field _resin_compat_class_0:Ljava/lang/Class; 3: dup 4: ifnonnull 18 7: pop 8: ldc_w 0000219; //String com.caucho.doc.JavadocRedirectServlet 11: invokestatic 0000225; //Method java/lang/Class.forName:(Ljava/lang/String;)Ljava/lang/Class; 14: dup 15: putstatic 0000221; //Field _resin_compat_class_0:Ljava/lang/Class; 18: areturn 19: aconst_null 20: areturn Exception table: from to target type 0 19 19 Class java/lang/ClassNotFoundException Since this seems to be a regular try - catch implementation, one would expect to see the code "astore_0" between instruction 18 and 19. After instrumentation, this leads to a verify error "Inconsistent stack height 2 != 1" Any information on how this was compiled would be appreciated. |
